China's Zhou Lulu added to China's ever-growing gold medal tally at the London Games on Sunday, winning the women's over-75-kilogramme weightlifting competition with a world record. Zhou set the world record with a combined 333kg, beating Russian Tatiana Kashirina by just 1kg. Kashirina, who managed a world record in the snatch portion with 151kg, seemed on course to win the gold as she took the world record to 332kg - only to see Zhou grab gold when she managed an Olympic record of 187kg in the clean and jerk.
